• Dissolved oxygen meter is a precision instrument for measuring dissolved oxygen and temperature. The dissolved oxygen probe is a thin film with a polarographic sensor and a thermistor for temperature measurement and temperature compensation. The permeable membrane separates the measured solution from the sensing electrode but allows oxygen to pass through the membrane to react, and the concentration can be measured.
• Dissolved oxygen refers to the concentration of molecular oxygen dissolved in water, generally expressed in mg/L (ppm) and saturation percentage (%), which is the percentage of dissolved oxygen in 1L of water. The oxygen concentration of our dissolved oxygen meter is 0.0-40.0mg/L, most of the range of dissolved oxygen meters on the market is 0.0-20mg/L. When measuring and calibrating, needn't open the protective cover of the electrode, just put the electrode in the solution for measurement.
• Detachable probe, easy to replace, equipped with 6 probe protective covers. The film inside the protective cover cannot be taken apart. After using for a period of time, the test value is inaccurate and the calibration is still inaccurate, and the membrane sleeve needs to be replaced.
• Adopts the digital screen display with backlight, which is more clear and convenient to read data. Auto power-off in 8 minutes if not using it. Low battery indication. Oxygen solubility will be affected by temperature, atmospheric pressure, and salinity. Our instrument with temperature compensation can meet normal use.
• It is very suitable for measuring the dissolved oxygen level and temperature in a wide range of aquariums, swimming pools, ponds, freshwater aquaculture, marine aquaculture, school teaching experiments, laboratory sterile environment, aquaculture, scientific research, and other fields.

• Taking TDS MeasurementsRemove the protective cap.
• Turn the TDS meter on. The ON/OFF switch is located on the panel.
• Immerse the meter into the water/solution up to the maximum immersion level (2 inch).
• Lightly stir the meter to dislodge any air bubbles.
• Wait until the display stabilizes. Once the reading stabilizes (approx. 10 seconds), press the HOLD button to view the reading out of the water.
• If the meter displays a flashing x10 symbol, multiply the reading by 10.
• After usage, shake off any excess water from your meter. Replace the cap.
• Taking Temperature MeasurementsOnce the meter is on, the temperature function can be used at any time, in or out of liquid.
• Press the TEMP button. The display will switch to temperature (in Celsius only).
• To return to TDS mode, press the TEMP button.PrecautionsThe meter is not water-tight. Do not dip the meter beyond the water level limit.
• Do not store the meter in high temperatures or direct sunlight.
• Do not attempt to open the housing or tinker with the electronics of the unit.
• After multiple usage, if the product is not showing correct readings, please use the recalibaration guidelines as given below.
• Re-calibration GuidelinesImmerse the TDS Meter into Calibration solution up to maximum immersion level (2 inch)Reading appear on the Display.
• If the meter does not read within 2% of solution. Press Temp key for 3 seconds, Display Start Blinking. Adjust the reading by using “Temp” key (to increase the reading) and hold key (to decrease the reading)Press Temp key again for 3 seconds, meter enters in Testing Mode. Take the TDS Meter out from water Wait a moment, after showing Zero put the meter again into water. TDS Meter show Readings.
• If Reading is accurate calibration is completed. If not, repeat the procedure

• Test the pH level of solution/water and make your living healthier.
• Pocket size, lightweight and portable.
• Very wide variety of applications, used for testing the acidity and alkaline levels of almost any liquid.
• ATC function(Automatic temperature compensation) and clear backlight LCD display.
• Apply in water sources, soil-free growing, aquarium, hydroponics, laboratory, spas, swimming pools and other water systems.
